Voltammetric characterisation of polyelectrolyte adsorption/transfer at the watermid1,2-DCE interface

The voltammetric characterisation of aqueous soluble polyelectrolytes at the watermid1,2-dichloroethane interface was investigated. The polyelectrolytes studied included poly (diallyldimethylammonium chloride) (PDADMACl) and polyethylenimine (PEI). The adsorption process followed by the transfer of these polyelectrolytes across the interface was characterised. The observable transfer of the monomer cation of the PDADMA+, namely diallyldimethylammonium (DADMA+) ion, was compared to that of the polyelectrolyte transfer process. Physical data including the diffusion coefficient and the Gibbs energy of transfer across the watermid1,2-dichlorethane interface was evaluated for both the polycation and monocation.
